a modeling approach to assess coastal management effects on benthic habitat quality a case study on coastal defense and navigability
Estuarine Coastal and Shelf Science, 2017Co-Authors: Francesco Cozzoli, Patrick Meire, S Smolders, Menno Eelkema, Tom Ysebaert, Vincent Escaravage, Stijn Temmerman, Peter M J Herman, Tjeerd J BoumaAbstract:The natural coastal hydrodynamics and morphology worldwide is altered by human interventions such as embankments, shipping and dredging, which may have consequences for ecosystem functionality. To ensure long-term ecological sustainability, requires capability to predict long-term large-scale ecological effects of altered hydromorphology. As empirical data sets at relevant scales are missing, there is need for integrating ecological modeling with physical modeling. This paper presents a case study showing the long-term, large-scale macrozoobenthic community response to two contrasting human alterations of the hydromorphological habitat: deepening of estuarine channels to enhance navigability (Westerschelde) vs. realization of a Storm Surge Barrier to enhance coastal safety (Oosterschelde). A multidisciplinary integration of empirical data and modeling of estuarine morphology, hydrodynamics and benthic ecology was used to reconstruct the hydrological evolution and resulting long-term (50 years) large-scale ecological trends for both estuaries over the last. Our model indicated that hydrodynamic alterations following the deepening of the Westerschelde had negative implications for benthic life, while the realization of the Oosterschelde Storm Surge Barriers had mixed and habitat-dependent responses, that also include unexpected improvement of environmental quality. Our analysis illustrates long-term trends in the natural community caused by opposing management strategies. The divergent human pressures on the Oosterschelde and Westerschelde are examples of what could happen in a near future for many global coastal ecosystems. The comparative analysis of the two basins is a valuable source of information to understand (and communicate) the future ecological consequences of human coastal development.

Effect of sedimentological and hydrodynamical changes in the intertidal areas of the Oosterschelde estuary (SW Netherlands) on distribution, density and biomass of five common macrobenthic species: Spio martinensis (Mesnil), Hydrobia ulvae (Pennant),
Hydrobiologia, 1994Co-Authors: J. Coosen, Patrick Meire, J. Seys, J.a.m. CraeymeerschAbstract:In order to evaluate the impact of the construction of the Storm-Surge Barrier and secondary dams on macrobenthos of the tidal flats in the Oosterschelde (SW Netherlands), changes in distribution, density and biomass of five common species (Spio martinensis, Hydrobia ulvae, Arenicola marina, Scoloplos armiger and Bathyporeia sp) were analysed.

spatial and temporal patterns of intertidal macrobenthic populations in the oosterschelde are they influenced by the construction of the Storm Surge Barrier
Hydrobiologia, 1994Co-Authors: J. Seys, Patrick Meire, John Buijs, J. CoosenAbstract:The construction of a Storm-Surge Barrier in the mouth of the Oosterschelde caused important hydrodynamical and morphological changes that could influence the macrobenthic populations. This paper is one in a series of five all dealing with the effects of the Storm-Surge Barrier on macrozoobenthos and analyses the spatial and temporal distribution of macrozoobenthos in the Oosterschelde and its relationship with some environmental parameters, based on two large scale sampling campaigns, one before and one after the completion of the Barrier.

long term changes 1979 89 in the intertidal macrozoobenthos of the oosterschelde estuary are patterns in total density biomass and diversity induced by the construction of the Storm Surge Barrier
Hydrobiologia, 1994Co-Authors: J. Coosen, Patrick Meire, J. Seys, J.a.m. CraeymeerschAbstract:To evaluate the effects of the construction of a Storm Surge Barrier in the Oosterschelde, long-term patterns (1979–89) in abundance and biomass of the intertidal macrozoobenthos were studied at 14 permanent stations. Additionally, data of a large-scale survey in late summer 1985 and 1989 were analysed. In this paper, patterns in general parameters are discussed.

Hydrobiologia, 1994Co-Authors: J. Seys, J. Coosen, Patrick Meire, J.a.m. CraeymeerschAbstract:To evaluate the effects of the construction of a Storm Surge Barrier in the Oosterschelde, long-term patterns (1919-89) in abundance and biomass of the intertidal macrozoobenthos were studied at 14 permanent stations. Additionally, data of a large-scale survey in late summer 1985 and 1989 were analysed. In this paper, patterns in general parameters are discussed. Late summer values of total biomass, total density, species richness, diversity and abundance- and biomass ratio show no overall significant trend during the study period. The changes in the hydrodynamics and the morphology of the Oosterschelde after the completion of the Storm Surge Barrier do not seem to have influenced the normal patterns in benthic populations

software engineering with formal methods experiences with the development of a Storm Surge Barrier control system
Formal Methods, 2008Co-Authors: Klaas Wijbrans, Franc Buve, Robin Rijkers, Wouter GeurtsAbstract:This paper revisits the experiences with the use of formal methods in the development of the control system for the Maeslant Kering. The Maeslant Keringis the movable Barrier which has to protect Rotterdam from floodings while, at almost the same time, not restricting shipping traffic to the port of Rotterdam. The control system, called BOS, completely autonomously decides about closing and opening of the Barrier and, when necessary, also performs these tasks without human intervention. BOS is a safety-critical software system of the highest Safety Integrity Level according to the IEC 61508 standard. One of the reliability increasing techniques used during its development is formal methods. This paper revisits the earlier published experiences with the project after the system is in operation for ten years and has performed its first autonomous Barrier operation on November 11th, 2007.

Software engineering with formal methods: The development of a Storm Surge Barrier control system revisiting seven myths of formal methods
Formal Methods in System Design, 2001Co-Authors: Jan Tretmans, Klaas Wijbrans, Michel ChaudronAbstract:This paper discusses the use of formal methods in the development of the control system for the Maeslant Kering. The Maeslant Kering is the movable dam which has to protect Rotterdam from floodings while, at (almost) the same time, not restricting ship traffic to the port of Rotterdam. The control system, called BOS, completely autonomously decides about closing and opening of the Barrier and, when necessary, also performs these tasks without human intervention. BOS is a safety-critical software system of the highest Safety Integrity Level according to IEC 61508. One of the reliability increasing techniques used during its development is formal methods. This paper reports experiences obtained from using formal methods in the development of BOS. These experiences are presented in the context of Hall's famous "Seven Myths of Formal Methods".

lessons from the application of formal methods to the design of a Storm Surge Barrier control system
Formal Methods, 1999Co-Authors: Michel Chaudron, Jan Tretmans, Klaas WijbransAbstract:We describe the experience of the industrial application of formal methods in the development of a mission critical system. We give a description of the system that was to be developed and the methods that were employed to realize the high level of reliability that was required. In this paper we will describe which formal techniques were used, how these techniques were used, the influence of formal methods on the development process and recommendations for managing the use of formal methods.
